Due to my inability to support HeaderTabs and other extensions that were created by/for Semantic Communities LLC, I discontinued the mailing list that was used for those extensions and instructed users to ask their questions here.
Hope Yaron and others can continue helping those users out here as they already do.
Thank you,
Sergey
